SUSAN: Oh, pet. Anything to help. I don't mind. I'll make the tea.

IBRAHIM: Did you make this tea?

SUSAN: I did, yes.

IBRAHIM: Don't make the tea.

RUBY: Who are you?

DOCTOR: I'm the Doctor.

FLOOD: Busy man, sweetheart. You and your box of tricks. You look like you've lost a pound and found a sixpence. What's wrong?

DOCTOR: Just wondering. Maybe I'm the bad luck.

DONNA: Was it me, or was Isaac Newton hot?

DOCTOR: He was, wasn't he? He was so hot. Oh! Is that who I am now?

DONNA: Well, it was never that far from the surface, mate. I always thought…

DOCTOR: It's funny, cos I wonder where the TARDIS goes at random. Maybe it lands on some outcrop by the sea. And there's a tribe and they worship it for 100 years. Then they grow up and try to burn it. Then they get wise. They preserve it. Then they build a city all around it, till the TARDIS is just a tiny little dot, surrounded by skyscrapers and monorails. Time passes and the city falls. It all gets swept away. And there's the TARDIS… still on its outcrop… by the sea. She's the only thing I've got left.

Not-Thing: My arms are too long.

DONNA: Have you got the controls set to "famous", or what?

DOCTOR: Oh, the blossomiest blossom. That's the only sad thing. I want to know what happens next. Right, then. Doctor Whoever-I'm-about-to-be. Tag, you're it.

DOCTOR: I know these teeth. What? What? What?!

TENTH DOCTOR: What? What?

SIXTH DOCTOR: What are you afraid will happen if you pause for breath?

TENTH DOCTOR: That there won't be another.

DOCTOR: It’s not about losing hope. It’s about never forgetting that hope's always there, even when you can’t see it.

DOCTOR: You don’t need me telling you your family isn’t always the one you were born in. Usually it is, and that’s great, that’s fantastic, but it’s not always like that, and that’s ok. And if you do find people who love you - hold on tight.

YASMIN: Make a wish and skim it.

DOCTOR: I wish...

YASMIN: You can't say your wish out loud!

DOCTOR: You can where I'm from. I wish... I wish this would go on forever.

DOCTOR: Two hearts. One happy, one sad.

RANI: You know what I think? I think it's not over, because I don't think she's dead. I really don't. That's not just me being mad, cos I honestly think in my heart and soul that he came back for her. Right at the end, the Doctor came back for his Sarah Jane, and he said, shall we go? Out into the stars? One last trip? And she said, oh yes please. And I think they're out there now, Sarah Jane and the Doctor in the TARDIS, travelling through space and time forever, in a story that never ends.

DOCTOR: None of us know for sure what's out there. That's why we keep looking. Keep your faith. Travel hopefully. The universe'll surprise you... constantly.

FIRST DOCTOR: There is good and there is evil. I left Gallifrey to answer a question of my own. By any analysis, evil should always win. Good is not a practical survival strategy - it requires loyalty, self-sacrifice and love. And so, why does good prevail? What keeps the balance between good and evil in this appalling universe? Is there some kind of logic? Some mysterious force?

BILL: Perhaps it's just... a bloke.

FIRST DOCTOR: A... bloke?

BILL: Yeah! Perhaps it's just some bloke, wandering around, putting everything right when it goes wrong.

FIRST DOCTOR: Well, that would be a nice story, wouldn't it?

BILL: That would be the best.

DOCTOR: Never be cruel. Never be cowardly. Hate is always foolish. Love is always wise. Always try to be nice, but never fail to be kind.

DOCTOR: Who I am is where I stand. Where I stand is where I fall.

DOCTOR: Winning? Is that what you think it's about? I'm not trying to win. I'm not doing this because I want to beat someone, or because I hate someone, or because, because I want to blame someone. It's not because it's fun and God knows it's not because it's easy. It's not even because it works, because it hardly ever does. I do what I do, because it's right! Because it's decent! And above all, it's kind. It's just that. Just kind. If I run away today, good people will die. If I stand and fight, some of them might live. Maybe not many, maybe not for long. Hey, you know, maybe there's no point in any of this at all, but it's the best I can do, so I'm going to do it. And I will stand here doing it till it kills me. You're going to die too, some day. How will that be? Have you thought about it? What would you die for? Who I am is where I stand. Where I stand, is where I fall. Stand with me. These people are terrified. Maybe we can help, a little. Why not, just at the end, just be kind?

DOCTOR: Oh, come on! Cheer up! It's not that hard. It's no harder than all these exams that you have to take these days. Except for Media Studies. It's going to be harder than that.

RAM: What about football?

DOCTOR: Unbelievably boring sport. Now, darts? Darts is something worth practising for. Maths and alcoholic beverages. The best way to spend a morning.

DOCTOR: Get back in the TARDIS, this is my job!

RIVER: This is my job!

DOCTOR: I've been doing it for longer!

RIVER: And I do it better!

DOCTOR: River, not one person on this ship, not one living thing is worth you!

RIVER: Or you!

DOCTOR: Nothing’s sad until it’s over, and then everything is.
